will -fall withinthe scope of the `hereto annexed' i claims;

disk fan,V as is well known, produces `blasts of-air which travel in Va spiral, "corkscrew-like direction. Y VThis causes the blasts passing through 'th'e apertures to strike portions of thermachine oninwardly travelling `or outwardly Itrai/Telling,

`glancing directions `depending on the lpoint wherethe blast strikes the machine. This results inl theblasts sweeping the portions of the machine inwardlyandoutwardly to more eiectivelyiclean the machine than if the blasts struck the machine while travelling in a straight line.

engages spring |48, it will press the spring backwardly until the resistance offered isv enough to slide therod |05 and to reverse the `direction; of

travel' of the mechanism on the trackway, A'and when the device reaches the` other. end. of its travel, the` members |45 and |41 will. likewise operate to reverse the direction of travel.4
